Headband



FIG. 1 is a front perspective view of a headband being worn on a person's head showing my new design;

FIG. 2 is a front perspective view of FIG. 1 shown without a person's head;

FIG. 3 is a slightly reduced left side view thereof;

FIG. 4 is a slightly reduced right side view thereof; and,

FIG. 5 is a top plan view thereof.

The broken line showing of a human head in FIG. 1 is for illustrative purposes only and forms no part of the claimed design. 

I claim the ornamental design for a headband, as shown and described.
